[vm/aot] Add a custom ELF loader in dart_precompiled_runtime.
...
Also switch some CQ bots using blobs to ELF. Once all embedders have migrated, we will remove blobs
support entirely.

Rename TARGET_OS_* to HOST_OS_*.
...
Like HOST_ARCH_*, HOST_OS_* describes the OS the VM is running on, which may be different from the OS the VM is generating code for during AOT compilation.
Currently we conflate the two when emitting AOT as assembly, and we get away with it because Flutter only uses assembly for targeting iOS and one can only target iOS from a Mac, but we expect to use assembly for Android as well so native tools can unwind Dart frames.

Use a single file for app snapshots.
...
For blobs, put all four pieces into a single file with a header describing their offsets.
For dynamic libraries, move the vm isolate and isolate pieces into the dynamic library as additional read-only sections.
Automatically detect if the script argument is an app snapshot and initialize the VM appropriately, similar to automatic detection of script snapshots.
